Njira zothetsera mavuto ogwiritsira ntchito galasi sealant m'nyengo yozizira

Chifukwa cha kutentha kochepa m'nyengo yozizira, ndi mavuto otani omwe mungakumane nawo mukamagwiritsa ntchito magalasi osindikizira kumalo otentha kwambiri? Kupatula apo, galasi sealant ndi zomatira kutentha kwa chipinda komwe kumakhudzidwa kwambiri ndi chilengedwe. Tiyeni tiwone momwe magalasi amagwiritsidwira ntchito m'nyengo yozizira yotentha. 3 mafunso wamba!

 

 

1. Chisindikizo cha magalasi chikagwiritsidwa ntchito kumalo otentha otsika, vuto loyamba ndikuchiritsa pang'onopang'ono

 

Kutentha ndi chinyezi cha chilengedwe chimakhala ndi mphamvu yochiritsa. Kwa zosindikizira zamtundu umodzi wa silicone, kutentha kwapamwamba ndi chinyezi, kumapangitsanso kuthamanga kwa machiritso. M'nyengo yophukira ndi yozizira, kutentha kumatsika kwambiri, zomwe zimachepetsa kuchiritsa kwa silicone sealant, zomwe zimapangitsa kuti nthawi yowuma pang'onopang'ono komanso kuchiritsa kwambiri. Nthawi zambiri, kutentha kukakhala pansi pa 15 ° C, kuthamanga kwa machiritso kumakhala kocheperako. Kwa khoma lachitsulo chotchinga chachitsulo, chifukwa cha kuchiritsa pang'onopang'ono kwa chosindikizira m'dzinja ndi m'nyengo yozizira, pamene kusiyana kwa kutentha pakati pa usana ndi usiku ndi kwakukulu, mipata pakati pa mbale idzatambasulidwa kwambiri ndi kupanikizidwa, ndipo chosindikizira pamalumikizidwe. mosavuta kuphulika.

 

2. Glass sealant imagwiritsidwa ntchito kumalo otentha otsika, ndipo kugwirizana pakati pa guluu wa galasi ndi gawo lapansi kumakhudzidwa.

 

Pamene kutentha ndi chinyezi kumachepa, kumamatira pakati pa silicone sealant ndi gawo lapansi kudzakhudzidwanso. Nthawi zambiri oyenera chilengedwe chomwe silikoni sealant imagwiritsidwa ntchito: zigawo ziwiri ziyenera kugwiritsidwa ntchito pamalo oyera pa 10 ° C ~ 40 ° C ndi chinyezi 40% ~ 60%; chigawo chimodzi chiyenera kugwiritsidwa ntchito pa 4 ° C ~ 50 ° C ndi chinyezi wachibale 40% ~ 60% ntchito pamalo aukhondo ozungulira. Kutentha kukakhala kocheperako, kuchuluka kwa machiritso ndi kuyambiranso kwa chosindikizira kumachepa, ndipo kunyowa kwa chosindikizira ndi pamwamba pa gawo lapansi kumachepa, zomwe zimapangitsa kuti nthawi yayitali yosindikizira ipange mgwirizano wabwino ndi gawo lapansi.

 

3. Glass sealant imagwiritsidwa ntchito kumalo otsika kutentha, ndipo guluu wa galasi ndi wokhuthala

 

Kutentha kumachepa, silicone sealant imakula pang'onopang'ono ndipo extrudability idzakhala yosauka. Kwa zisindikizo zamagulu awiri, kuwonjezereka kwa chigawo A kudzachititsa kuti makina a glue awonjezereke, ndipo kutulutsa guluu kudzachepa, zomwe zimapangitsa guluu wosakhutira. Kwa chigawo chimodzi chosindikizira, colloid imakhuthala, ndipo kupanikizika kwa extrusion kumakhala kwakukulu panthawi yogwiritsira ntchito mfuti ya glue kuti muchepetse mphamvu ya ntchito yamanja.

 

Momwe mungathetsere

 

Ngati mukufuna kumanga m'malo otentha kwambiri, choyamba yesetsani kuyesa guluu waung'ono kuti mutsimikizire kuti guluu wa galasi akhoza kuchiritsidwa, kumamatira kuli bwino, ndipo palibe vuto la maonekedwe musanayambe kumanga. kutentha kwa malo omanga asanamangidwe
